It has been rereleased for 3ds, my cousin has it.

Also, if you've got a nintendo wii it's pretty cheap on the virtual console. I emulate it on project64 (legally... I bought it on the virtual console then there's a way to extract the rom from that)

Just one last tidbit for it. The guy who designed all the sidequest said that he incorporated every type of situation or problem for a character to get into that he had EVER experienced or witnessed in his real life, everything. From a family friendly filter of course. (he was in his 30's at the time)
